MS3 series electronic soft starters for squirrel cage motors are versatile and compact in a robust built housing. Integrated by pass and current measurement you save wiring and external components. The soft starters have five front potentiometers that allow setting up the start/stop time and voltage along with maximum current. To save wiring time and costs, the auxiliary supply is produced internally from the mains supply. MS3 series soft starters are designed with integrated phase reversal protection and are a versatile tool for regular and heavy-duty starting processes.
